• When viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. Hence, these are also known as striped or striated muscles.
  
• Striated muscle or skeletal muscle is the most common and widely distributed muscle tissue in the body. 
• It forms all the skeletal muscles, such as the biceps. Striated muscle is a voluntary muscle. All conscious movements of the body, including the movement of the arm, legs, facial expressions, eye movements, and swallowing, are the result of the skeletal or striated muscle tissue.

• A- epidermis, B-  phloem, C- xylem, D endodermis. 
• When a leafy shoot of a plant is put in the coloured solution, the coloured solution will be absorbed and transported by the xylem in the vascular bundle to all other plant parts by transpiration pull, which acts like a suction pressure inside the xylem.
• The xylem vessel becomes coloured as it has conducted water from the dyed solution.

The correct option is C.

The given figure is that of stomata. Stomata are found in the epidermis, the outermost protective layer. They help in gaseous exchange and also in transpiration. They are surrounded by the guard cell.

• Smooth muscle cells are spindle shaped, uninucleate, unbranched and involuntary in nature. 
• The cells are arranged in sheets one above the other.
• Smooth muscle is found in the walls of hollow organs like your intestines and stomach
  

Tendons allow a bone to move. They are fibrous connective tissues that attach muscles to bones. 

Hence, the correct option is B.

Connective tissue contains loosely spaced cells that are embedded in the rigid, jelly-like, fluid or dense matrix. 
Bone cells are embedded in a hard matrix which is made up of salts of calcium and phosphate. 
Cartilage has widely spaced cells and interspersed in a matrix made of proteins and sugars. It covers the ends of bones at a joint. 
Hence, both bones and cartilage are types of connective tissue. 

• Nerve cells or neurons are the longest cells of the body. They form the structural and functional unit of the nervous system. 

• Nerve cells do not form layers and are structurally separated from one another, but can communicate through the synapse.

• Epithelial cells, muscle cells, and gland cells are arranged in layers.

So, the correct answer is option 'C'.

A ligament is the fibrous connective tissue that connects bones to other bones. Ligaments are similar to tendons as they are all made of connective tissue. The differences in them are the connections that they make. Ligaments connect one bone to another bone while the tendons connect muscle to bone. These are all found in the skeletal system of the human body.
